Abstract

Abstract A nozzle assembly including a nozzle and means for preventing escape of liquid and vapor from the area adjacent the nozzle outlet. In one preferred form, a nozzle has a closure plug adjacent its discharge outlet and has means for biasing the closure plug to close the inlet of the receiver into which the nozzle discharge outlet is placed. Liquid coming out the receiver inlet, for example due to splash-back, is urged by the closure plug to return to the receiver inlet. Preferably, also, a fluid collector is provided adjacent the closure plug to temporarily retain liquid fuel in excess of that which can immediately be returned to the receiver inlet so that such excess is held in the fluid collector until it can drain back into the receiver inlet. If desired, fluid coupling means can be provided to provide fluid communication from the fluid collector to a fluid disposal. Excessive liquid in the fluid collector and vapors can thus be drawn to the fluid disposal.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 191 words
A nozzle assembly for delivery of liquid from a source to a liquid receiver having an inlet, said nozzle assembly comprising: a nozzle including a nozzle inlet adapted for connection to a source of liquid, a nozzle outlet, a nozzle housing coupling said nozzle inlet and said nozzle outlet, and control means for controlling liquid flow from said nozzle inlet through said nozzle housing to said nozzle outlet; closure means coupled to said nozzle adjacent said nozzle outlet for substantially closing a liquid receiver inlet, with the nozzle outlet within the liquid receiver inlet for delivery of liquid thereinto; a fuel collector adjacent said closure means for retaining liquid passing said closure means from the area adjacent said nozzle outlet, said fuel collector includes a first shell member and a second shell member cooperating with said first shell member to provide a rotational interface between said fuel collector and said closure means; and means defining a fluid path communicating through said closure means and to said fuel collector and adapted for connection to a fluid disposal for providing fluid communication from an area adjacent said nozzle outlet to the fluid disposal.
Claim 2
Dependent Claim 191 words
A nozzle assembly for delivery of liquid from a source to a liquid receiver having an inlet, said nozzle assembly comprising: a nozzle including a nozzle inlet adapted for connection to a source of liquid, a nozzle outlet, a nozzle housing coupling said nozzle inlet and said nozzle outlet, and control means for controlling liquid flow from said nozzle inlet through said nozzle housing to said nozzle outlet; closure means coupled to said nozzle adjacent said nozzle outlet for substantially closing a liquid receiver inlet, with the nozzle outlet within the liquid receiver inlet for delivery of liquid thereinto; a fuel collector adjacent said closure means for retaining liquid passing said closure means from the area adjacent said nozzle outlet, said fuel collector includes a first shell member and a second shell member cooperating with said first shell member to provide a rotational interface between said fuel collector and said closure means; and means defining a fluid path communicating through said closure means and to said fuel collector and adapted for connection to a fluid disposal for providing fluid communication from an area adjacent said nozzle outlet to the fluid disposal.
Claim 3
Dependent Claim 87 words
A nozzle assembly as claimed in claim 1 in which said fuel collector comprises a bellows encircling a portion of said nozzle and first fluid passage means for providing fluid communication from the area adjacent said nozzle outlet through said closure means and to the interior of said bellows, and in which said defining means comprises second fluid passage means connected to said bellows and adapted for connection to a fluid disposal for providing a fluid path from the interior of said bellows to the fluid disposal.
Claim 4
Dependent Claim 31 words
